Dear music lover,

thank you for purchasing a PRO-JECT AUDIO record player.

In order to achieve maximum performance and reliability with this record player you should study these instructions

for use carefully.

Warning of a hazard for the user, the unit or possible misuse.

Important notice.

** Your turntable has been delivered with a factory fitted and adjusted cartridge, please ignore the

cartridge set up instructions unless changing the cartridge at a later date.

During assembly and adjustment of the deck small parts could be lost if not carefully placed in a suitable

receptacle. Before starting assembly make yourself acquainted with the parts listed above and correspondingly

numbered in the technical drawings above. Separately packed items are marked with an asterisk *.

Set-up

Make sure the surface you wish to use the turntable on is level (use a spirit level) before placing the turntable on it.

Remove the two red transport screws (1) which secure the motor (22) during transportation.

Remove the transport lock (18) from the tonearm. Store it together with the two red motor transport screws

(1) in the original packaging so they are available for any future transportation.

Fit the drive belt (3) around the hub (4) and the smaller diameter part of the motor pulley (2). Avoid getting

sweat or grease on the belt as these will deteriorate the performance and reduce the belt's lifespan. Use

absorbent kitchen paper to remove any oil or grease from the outer edge of the hub and the belt. Fit the

platter (5) and felt mat over the spindle of the hub (4).

Cartridge downforce adjustment

The counterweight (6) supplied is suitable for cartridges weighing between 3,5 - 5,5g. Alternative

counterweights for cartridges weighing between 6 - 9g or 1,5 - 3g are available as accessory parts. Adjust the

downforce prior to installing the anti-skating weight.

Pushing carefully, turn the counterweight (6) onto the rear end of the tonearm tube (9), and so that the

downforce scale (6a) shows towards the front of the player. Lower the armlift and position the cartridge in the

space between arm rest and platter. Carefully rotate the counterweight (6) until the armtube balances out.

The arm should return to the balanced position if it is moved up or down. This adjustment must be done

carefully. Do not forget to remove the cartridge protection cap if fitted.

Once the arm is correctly balanced return it to the rest. Hold the counterweight (6) without moving it, and gently

revolve the downforce scale ring (6a) until the zero is in line with the anti-skating prong (15). Check whether the

arm still balances out.

Rotate the counterweight counter clockwise (seen from the front) to adjust the downforce according to the

cartridge manufacturer's recommendations. One mark on the scale represents 1 mN (= 0,1g / 0,1 Pond) of

downforce.

The recommended downforce for the factory fitted cartridge is 17,5mN.

Anti-skating force adjustment

The anti-skating force must be adjusted according to the mass of the cartridge

as follows:

Downforce

Groove in the stub (15)

10 - 14mN 1

from bearing rings

15 - 19mN 2

" " "

20mN and bigger

" " "

Slip the loop of the anti-skating weight's thread over the third groove of the stub to set the correct anti-skating

force for the factory-fitted cartridge. Feed the thread through the loop of the wire support (17).

Connection to the amplifier

The record player has a captive tonearm signal lead (14) for connection to the amplifier. Use the Phono input

(sometimes labelled gram, disc or RIAA) on your amplifier. Make sure that the phono input offers correct matching

and amplification for the type of cartridge used. Line inputs (such as CD, Tuner, Tape or Video) are not suitable.

Take care to connect the left and right channels correctly. The right channel is usually marked red, the left

channel black or white. Check the manual supplied with your amplifier for relevant information. The earthing

wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided).

If your amplifier does not have an input suitable for phono cartridges you will require a separate phono

amplifier stage for MM or MC cartridges such as the PRO-JECT PHONO BOX or the PRO-JECT TUBE BOX

which is then connected between the record player and a free line level input of the amplifier.

For detailed product information please refer to the Pro-Ject web site www.project-audio.com.

The recommended load resistance for the factory fitted cartridge is: 47kohms/MM-input

Mains power connection

The turntable is supplied with a power supply suitable for your country's mains supply. Check the label before

connecting to ensure compliance with the mains rating in your house.

Connect the low voltage plug from the power supply to the socket (13) on the rear of the record player before

connecting the power supply to the mains.

Fitting the lid

Fit the lid (dust cover 10) carefully over the hinge prongs and adjust the screws (12) until the lid stays open

where you want it to without being too stiff to open or close.

Switching on and off

Pressing the power switch (20) alternately starts or stops the motor.

Changing replay speed

To play records at 45 r.p.m. first remove the platter (5). Using the accessory tool provided (3a), hook the belt

(3) over the larger diameter part of the motor pulley (2). Refit the platter. To revert to 33,33 r.p.m. repeat the

proceedings using the smaller step on the pulley.

When the Pro-Ject Speed Box ore the Speed Box SE are used speed change between 33 and 45 r.p.m.

is electronic. There is no need to move the belt manually. For further information see the last page.

*** In addition, 78 r.p.m. is available after fitting a special pulley, which may be purchased as an

optional extra.

For detailed product information please refer to the Pro-Ject web site www.project-audio.com.

Maintenance and cleaning

Your record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic

cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic

cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber

parts. It is recommended to fit the needle cover before cleaning or maintenance is carried out to avoid damage.

If the player is not used over a long period of time the drive belt can be removed to prevent unequal stretching.

Always disconnect the record player from the mains power supply as a precaution before maintenance!

Useful tips

The record player should be positioned on a low-resonance surface such as wood or multiple layer ply board

to avoid structural vibrations disturbing replay.

Fitting and connecting the cartridge

** All cartridges with half inch mounting holes can be fitted. Leaving the needle's protection cover on, fit the

cartridge to the headshell using the screws supplied with the cartridge by passing one screw through each

slot in the headshell (21). Do not tighten the nuts yet.

Connect the tonearm wires to the cartridge pins as follows:

white left channel positive (L+)

red right channel pos. (R+)

green right channel return (R -)

blue left channel return (L -)

The full sound quality of the record player can only be achieved if the cartridge is correctly adjusted. Particular

tools like the PRO-JECT alignment tool are required to accomplish this job properly..

If you are not well acquainted with the adjustment of cartridges you are advised to call upon the willing help of

your PRO-JECT dealer to accomplish this task for you.

Adjusting the azimuth

** The cartridge needle must be vertical in the record groove in order to trace

the groove wall modulations correctly.

A small screw at the bearing end of the arm allows incorrect azimuth to be

corrected if your needle is not mounted exactly perpendicular to the cartridge

body (which is often the case).

Slacken off the screw just enough to be able to revolve the arm tube without

applying force. Note! Do not remove the screw completely!

Screw

With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e. perpendicular

to the record's surface). Ideally this should correspond to the top surface of the cartridge body being parallel

to the record surface. When you are satisfied that the needle is vertical retighten the screw carefully.

Under no circumstances should the arm tube be adjusted with the needle still in the record groove!

Irreparable damage may be caused to the cantilever suspension! The arm must be lifted to make

each adjustment and lowered afterwards to check it.

Potential incorrect use and fault conditions

PRO-JECT turntables are manufactured to the highest standards and undergo strict quality controls before

leaving the factory. Faults that may possibly occur are not necessarily due to material or production faults but

can sometimes be caused by incorrect use or unfortunate circumstances. Therefore the following list of common

fault symptoms is included.

The platter doesn't turn although the unit is switched on:

The unit is not connected to the mains power supply.

No mains at the socket.

Drive belt is not fitted or has slipped off.

No signal through one or other channel or both channels:

No signal contact from the cartridge to the internal tonearm wiring or from that to the arm lead or

from that to the phono box or between that and the amplifier. This could be due to a faulty plug,

broken wire or solder joint or simply loose plug/socket connection.
